Interesting hard puzzle

[Sansen]

I was shown today a very interesting puzzle that even engines can't find. I believe it is a puzzle mainly for 2200 rated players and above. I hope you enjoy it

[FEN "n2Bqk2/5p1p/p4KP1/5Q2/8/8/8/8 w - - 0 1"]


White to move and win!

1. Qc8 Kg8 2. Bc7 Qxc8 3. gxf7 Kh8 4. Be5 Qc5 5. Ba1 Nc7 6. Bb2 a5 7. Ba1 a4 8. Bb2 a3 9. Ba1 a2 10. Bb2 a1= 11. Bxa1 1-0

That was amazing ..

Woah!
Whoever did this move has lots of skill!

Is this possible?

Qc5+ Kg8 gxh7+ Kxh7 Qh5+ Kg8 Qg7# It might be dumb but it looks easier and simpler to me!

The line can't be right, the queen can't move from h5 square to the g7 square

that is a difficult puzzle, should ask kasparov...

I think he meant Qh5+ Kg8 Qg5+ K any Qg7#
but...
Qc5+? Kg8 gxh7+ Kh8!
note: this is a kind of tactic for defending in the middle game (espesially when castled on opposite sides)

This is really amazing
Btw thanks for the solution, I would never have solved this not even in a whole life

Amazing. How bizarre queen sac, though. XD
